Why do we get brain freeze?
Show answer & explanation
Answer: Blood vessels rapidly change
Ice cream numbs nerves — Wrong. Nerves aren't numbed—they're actually overstimulated by rapid temperature change.
Blood vessels rapidly change ✓ — Correct! Cold food touching the roof of your mouth causes blood vessels to rapidly constrict then dilate. This triggers pain receptors. Your brain interprets this as head pain. Pressing your tongue to the roof of your mouth can help!
Cold damages brain cells — Wrong. No brain damage occurs. It's a temporary pain response from blood vessel changes in your mouth.
